After a bunch of research and experimentation, I found the best results for removing permanent pen is to use a dry-erase marker. Heavily color over the permanent pen (in a swirling motion) with the dry-erase marker and then just wipe off with a rag. Sounds too easy to be true, but it works. You will still see some remnants of the marker because the disc is porous and it is impossible to get it all out, but you will be amazed at how well this actually works. The hair-spray trick is ok, but this is much more effective. TRY IT!

Hey Fritz, try it on some Dx and KC Pro rocs. I'm curious if the dry erase marker will stain the plastic.

I recall seeing this technique used to remove sharpies from dry erase boards, usually 100% successfully. Really, anything that will redissolve the sharpie ink should work fine. It's the sharpie that has already sunk in the plastic that escapes the clutches of whatever solvent is used.

I always use acetone simply because it doesn't have any dye in it already. I have noticed that a few markings just refuse to come off, including the recorded weight pictured above. I would like to see if the dry erase technique works for those, maybe pick up a marker or two.

Thats the trick ChUck. The dry-erase marker redisolves the permanent...same as if you were to take another permanent marker and write over the top, it liquifies the old writing. I found the trick when I googled permanent ink removal. It works almost 100% on most other plastic objects!(a good tip if you have kids!) I stay away from acetone because I noticed it seems to actually affect the plastic if left on too long or used too much. I used acetone for dying for a while because of this (it opens up the pores in the plastic), but the color faded way too quickly. If used too much, the pores don't seem to close. It is extremely minimal, but you can feel the difference when you grip the disc...it is much grippier. That may sound good, but a few of my discs flew differently (much more understable) and I am not sure if it was because of the acetone or I just F'd them up somehow during the dye process. If it is just for marker, I doubt that will affect the disc in any way harmful I am sure.

I just tried it on some QJ's I got from Solty that had ink and it faded the ink, but didn't remove it. I think it was cause the ink had been on there so long. But it faded it significantly. That Marker trick is awesome!
